K68852819: Linux kernel vulnerability CVE-2016-10200

Security Advisory

Original Publication Date: May 02, 2017
Updated Date: Dec 18, 2018

Security Advisory Description

Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel
before 4.8.14 allows local users to gain privileges or cause a denial of
service (use-after-free) by making multiple bind system calls without properly
ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/
l2tp_ip.c and net/l2tp/l2tp_ip6.c. (CVE-2016-10200)

Impact

An attacker with administrative command line access may be able to perform a
use-after-free exploit to cause a denial of service (DoS) or gain system
privileges.

Security Advisory Status

F5 Product Development has assigned ID 659142 (BIG-IP) to this vulnerability.
Additionally, BIG-IP iHealth may list Heuristic H68852819 on the Diagnostics >
Identified > High page.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.

To determine the necessary upgrade path for your BIG-IQ system, you should
understand the BIG-IQ product offering name changes. For more information,
refer to K21232150: Considerations for upgrading BIG-IQ or F5 iWorkflow systems
.

Mitigation

To mitigate this vulnerability, you should permit management access to F5
products only over a secure network and restrict command line access for
affected systems to trusted users. For more information about restricting
access to the BIG-IP system, refer to K13092: Overview of securing access to
the BIG-IP system.
